What Are Ceramic Engines

Ceramic parts for gas turbine engines may be practical.

What are ceramic engines.

Here is an article on the prospects for an adiabatic turbo diesel from 1987 adiabatic diesel engine technology in future transportation. Some high performance engines might have ceramic parts or coatings usually on exhaustors and on the connecting rod although that s for reducing friction. Currently even blades made of advanced metal alloys used in the engines hot section require cooling and careful limiting of operating temperatures. Cre s near adiabatic ceramic rotary engine should be 1 more efficient 2 a lot smaller and yet more powerful 3 smoother running and 4 cleaner burning emitting less pollutants.

They withstand chemical erosion that occurs in other materials subjected to acidic or caustic environments. Ceramic engine is a direction. Interest in and experimentation with ceramics in the internal combustion engine ice goes way back. Turbine engines with ceramic parts or ceramic coated metal parts are currently in operation as auxiliary power sources.

Also to the toyota gtv line. In 1982 isuzu aska tested a car with an all ceramic engine near the kinko bay. Ceramic engines allow the compression and expansion of gases at extremely high temperatures without loss of heat or engine damage. In 1988 toyota introduced it s ceramic engine into its toyota crown line.

The only ceramic engine available would be some ceramic made up of bubbles that had walls very thin so the flexibility would exceed the strength. Making a whole engine of ceramic material though would be ridiculous. This is an inevitable choice because metal was the only choice at that time. The high strength heat resistance and reliability of the metal make it the perfect choice for engine parts.

They loose little heat operate at higher temperatures burning more fuel and pollute less. For a survey of the issues involved in adapting ceramics for demanding structural applications see advanced structural ceramics. A ceramic material is an inorganic non metallic often crystalline oxide nitride or carbide material. Since the invention of gasoline and diesel engines in germany in the late 19th century car engines were made of metal.

Ceramic engines would use this energy more efficiently. Automotive ceramics are only one of several types of advanced structural ceramic. Turbine engines made with ceramics could operate more efficiently giving aircraft greater range and payload for a set amount of fuel.
